There is no problem when using a snippet.
However, when applied to my actual project, resizer is created as shown in the 3 pictures below.

The red circle is the part where the resizer is formed unlike the snippet.
Is there a way to get rid of the resizer?
Is it because my dhtmlx version is not up to date?

Please, try to update your dhx.Grid build.
If the problem still occurs for you after that, please, provide a complete demo, where the problem can be reconstructed locally.
